MOTOR.

Specification of Letters Patent.

Patented Apr. '7, 1914.

Application filed March 17, 1913. Serial No. 754,740.

To all whom t may concern Be it known that we, BUNKER STEWART and DAVIDB. STEWART, citizens of the United States, and residents of Garden City,in the county of Finney and State of Kansas, have invented a new anduseful Improvement in Motors, of which the following is a specification.

Our invention is an improvement in motors, and has for its object theprovision of a water motor adapted to be arranged in a flowing streamand provided with vanes for engagement by the water to rotate the wheel,so arranged that on one side of the wheel the said vanes willautomatically take a position at approximately right angles to thedirection of the flow, and on the other side will automatically take aposition approximately parallel with the direction of flo-w to offer theslightest possible amount of resistance to the said flow.

In the drawings Figure 1 is a top plan view of the improved motor, andFig. 2 is a section on the line 2 2 of Fig. 1.

The present embodiment of the invention comprises a vertical shaft orstandard 1, supported by a base 2, adapted tok be arranged on the bottom3 of a stream, and upper and lower frames are journaled on the standardor shaft. tops 4 and 5 are arranged on the shaft or standard, the stop 4being near the upper end thereof, while the stop 5 is near the lowerend. Each of the frames before mentioned, comprises a hub 6 engaging theshaftabove the adjacent stop, and concentric rings 7 and 8 respectivelyare connected to each other and to the hub by spokes 9. The rings 7 and8 are also connected by spokes 10, the said spokes being arrangedintermediate the spokes 9. The spokes 9 in the present instance arearranged at angular distances of 90 and the spokes 10 are also arrangedat angular distances of 90 with respect to each other and at angulardistances of 45 with respect to the spokes 9.

Two series of vanes are connected to the frames, an inner series 11, andan outer series 12, t-he series 11 being arranged between the ring 7 andthe hub, while the vanes 12 are arranged between the rings 7 and 8. Eachof the said vanes consists of a plate of a length to extend from nearthe base 2 to above the level of the water, and of a width correspondingapproximately to the distance between the rings, or bet-Ween the innerring and the hub.

The rings 7 and 8 are of such size that the rings 7 divide each of thespokes 9 into two approximately equal parts, that portion of each spoke9 between t-he hub and the ring 7 being of approximately the same lengthas that portion between the rings 7 and 8.

Each of the vanes 11 is hinged to a vertical rod 13, which connects therings 7 of the upper and lower frames, by means of hinges 14, the saidhinges being secured to the vanes by rivets 15 and engaging the rod 13near the ends thereof. Each of the said hinges 14 is adjacent to aframe, the upper hinges being just below the ring 7 of the upper frame,while the lower hinges are just above the ring 7 of the lower frame. Thevanes 11 are thus held in proper vertical position, and the said vanesare free to swing on the rods. Each of the vanes 12 is connected to arod 1G connecting the rings 8 of the upper and lower frames by means ofhinges 17, the said hinges being secured to the vanes by means of rivets18. The uppermost hinge 17 of each vane 12 is arranged just below thering 8 of the upper frame and the lowermost hinge of each of the saidvanes is arranged just above the ring 8 of the lowermost frame. Thehinges thus prevent vertical movement of the vanes and hold the saidvanes in proper vertical position.

The rods 13 are arranged adjacent to the spokes 9 and in such positionthat the vanes 11 may be closed against the portion of the spokesbetween the ring 7 and the hub 6. The rods 16 are arranged adjacent tothe outer ends of the spokes 9 and the outer ends of the spokes 10 andin such position that the vanes 12 may close against the spokes 10 andagainst those portions of the spokes 9 between the rings 7 and 8.

All of the vanes are arranged on the same side of the spokes and it willbe evident that with this arrangement the vanes on one side of the wheelwill be forced against the spokes of the frames by the current, while ont-he other side of the wheel the vanes will be forced away from the.said spokes as shown in Fig. 1. The rings 7 and 8 limit the openingmove-ment of the said vanes.

A reference to Fig. 1 will clearly demonstrate that when the wheel is inthe position of the said figure, the two vanes adjacent to the spoke 9,which is transverse to the current on one side of the wheel, will be atright angles to the direction of flow, and will be in Contact with thesaid spokes. The vanes on the opposite sideI of the wheel adjacent tothe spoke 9 in alinementV with the first-named spoke will be moved awayfrom the said spoke 9 and willcontact at their free edges with the rings7 and S. The said vanes will not be precisely parallel with thedirection of flow, but will be slightly inclined with respect thereto,so that the reaction of the current will tend to assist in the rotationof the wheel. A like statement applies to the vane 12 immediately inadvance of the first-named vane. The two vanes 11 and 12 on the upstream side of the wheel adjacent to the spoke 9 are also parallel withthe direction of iiow and offer no resistance to the current. As soonhowever, as the vanes mentioned move away from a position exactlyparallel with the current, the reaction tends to move the wheel forward,and the same statement applies to the vane 12 45 in advance. At no timeis there more t-han one vane that oifers any resistance to the forwardmovement of the wheel, and that is the vane adjacent to the spoke 9 onthe lower or down stream side of the wheel parallel with the directionof flow, and the said vane keeps this position but a slight length oftime, soon moving into a position at right-angles to the direction offlow.

The improved motor may be used either with water orany other liquid orfluid as for instance air, and while the said motor is shown forconvenience in a stream of water with its axis of V rotation in avertical position, it is obvious that the motor `might be used with theaxis of rotation horizontal, and in the air, the motor being operated bythe impingement of the air on the vanes.

A motor comprising-'a shaft or standard provided with spaced stops,frames sup# ported on the shaft at the stops, each frame comprisingahubj ournaled on the shaft and rings arrangedconcentrieally with the hub,spokes arranged at angular distances of 90o and connecting the hub andthe rings, other spokes arranged intermediate the firstnamed spokes andconnecting the rings, said rings being of a diameter such that theinnermost ring is at approximately half the distance between the hub andthe outermost ring, rods connecting theqinnermost rings adjacent to therstsnamed spokes, other rods connecting the outermost rings adj aoent tothe first-named spokes and adjacent to the last-named spokes, and vaneshinged to the rods and of a width to close against the adjacent spokes,said vanes extending above and below the frame. v
